A magnet 26 as a detection target portion is fixed to a lower end portion of the cam gear 24 by insert molding, and the magnet 26 rotates integrally with the cam gear 24. The sensor substrate can detect the magnetic force of the magnet 26, and detect the rotational position of the cam gear 24. The cam gear 24 is disposed at a reference rotational position (reference position).
A first stopper 28 (see fig. 3 a and B) as a first regulating member is disposed on the right side of the cam gear 24, and the first stopper 28 is disposed on the front side of the knob 18 (knob base 18A). The first stopper 28 is provided with a first stopper 28A having a substantially rectangular parallelepiped shape as a first limiting portion, and the first stopper 28A extends in the front-rear direction. The movement of the first stopper 28A in the left-right direction is restricted by the upper side of the plate 12, and the first stopper 28A is movable (slidable) in the front-rear direction. An approximately rectangular parallelepiped overlapping portion 28B is integrally formed on the front upper side of the first stopper portion 28A, and the overlapping portion 28B extends and protrudes leftward with respect to the first stopper 28, and is restricted from moving upward by the upper wall of the housing 16. The first stopper 28 has a first engaging surface 28C, which is a concave shape and is formed as a first engaging portion, from the rear side to the left side of the left end portion of the overlapping portion 28B, and the first engaging surface 28C is inclined in a direction toward the left side as it goes toward the front.
A second stopper 30 (see fig. 3 a and B) as a second regulating member is disposed on the lower left side of the first stopper 28, and the second stopper 30 is disposed on the front side of the knob 18 (knob base 18A). The second stopper 30 is provided with a second stopper 30A having a substantially rectangular parallelepiped shape as a second limiting portion, and the second stopper 30A extends in the front-rear direction.

The rear portion of the second stopper 30A protrudes upward with respect to the other portion, and the rear portion of the second stopper 30A protrudes upward with respect to the first stopper 28A of the first stopper 28. The overlapping portion 28B of the first stopper 28 overlaps the front upper side of the second stopper 30A, the overlapping portion 28B restricts the upward movement of the second stopper 30A, and the second stopper 30A restricts the downward movement of the overlapping portion 28B. A concave second engaging surface 30B as a second engaging portion is formed on the left side of the second stopper 30 except for the rear portion of the second stopper 30A, and the second engaging surface 30B is inclined in a direction toward the left as it goes toward the front.
A first spring 32 (coil spring, see fig. 3 a and B) as a first biasing mechanism is provided between the front portion of the first stopper 28 and the plate 12, and the first spring 32 is compressed to bias the first stopper 28 rearward. A second spring 34 (coil spring, see fig. 3 a and B) as a second biasing means is stretched between the front portion of the second stopper 30 and the plate 12, and the second spring 34 is compressed to bias the second stopper 30 rearward.
The first engaging surface 28C of the first stopper 28 is engaged (abutted) with the forward end portion of the first release surface 24A of the cam gear 24 by the urging force of the first spring 32, and the first stopper 28 is disposed at the first release position (the position where the first stopper 28A is separated from the knob 18 (knob base 18A) to the front side) in which the movement to the rear side by the urging force of the first spring 32 is restricted. The second engaging surface 30B of the second stopper 30 is engaged (abutted) on the opposite side of the forward end of the second release surface 24B of the cam gear 24 by the urging force of the second spring 34, and the second stopper 30 is disposed at the second release position (the position where the second stopper 30A is separated from the knob 18 (the knob base 18A) to the front side) with the movement to the rear side being restricted by the urging force of the second spring 34.
When the cam gear 24 is rotated in the opposite direction from the reference rotational position and disposed at the first operating position (see fig. 4A and B), the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first release surface 24A of the cam gear 24 to the first operating surface 24C, and the first stopper 28 is moved (operated) rearward from the first release position by the biasing force of the first spring 32 and disposed at the first moving position. The engagement target of the second engagement surface 30B of the second stopper 30 is maintained as the second release surface 24B of the cam gear 24, and the arrangement of the second stopper 30 at the second release position is maintained.
When the cam gear 24 is rotated in the opposite direction from the first operating position and is disposed at the second operating position (see fig. 5 a and B), the engagement target of the second engagement surface 30B of the second stopper 30 is changed from the second release surface 24B of the cam gear 24 to the second operating surface 24D, and the second stopper 30 is moved (operated) rearward from the second release position by the biasing force of the second spring 34 and is disposed at the second movement position. The engagement target of the first engagement surface 28C of the first stopper 28 is maintained as the first operating surface 24C of the cam gear 24, and the arrangement of the first stopper 28 at the first movement position is maintained.
A brake (not shown) of the vehicle is electrically connected to the control device as a restriction releasing portion, and the passenger operates the brake to brake the vehicle. A lock switch (not shown) as a restriction operation unit is electrically connected to the control device, and the lock switch enables a passenger to perform a locking operation (restriction operation) and an unlocking operation (restriction release operation).
Next, the operation of the present embodiment will be described.
In the shift device 10 configured as described above, the operation knob 18 is rotated, and the shift position of the knob 18 is changed to the "P" position, the "R" position, the "N" position, and the "D" position.
However, when the knob 18 is disposed at the "P" position (when the sensor substrate detects that the shift position of the knob 18 is at the "P" position), the motor is driven in reverse by the control of the control device in the shift lock mechanism 22 when the brake is not operated, and the cam gear 24 is rotated in the reverse direction via the transmission mechanism, so that the cam gear 24 is disposed at the first operating position from the reference rotational position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first release surface 24A of the cam gear 24 to the first operating surface 24C, and the first stopper 28 is moved from the first release position to the first movement position to the rear side by the biasing force of the first spring 32 (see fig. 4 (a) and (B) and fig. 6 (a) column). When the first stopper 28 moves to the first movement position (when the sensor substrate detects that the cam gear 24 is disposed at the first operation position), the reverse driving of the motor is stopped under the control of the control device. Thereby, the rear portion of the first stopper 28A of the first stopper 28 is inserted into the "P" hole 20A of the knob 18, the other direction side surface of the "P" hole 20A abuts on the first stopper 28A, and the rotation of the knob 18 from the "P" position to the one direction side (the "R" position side) is locked (restricted).
On the other hand, when the knob 18 is disposed at the "P" position (when the sensor substrate detects that the shift position of the knob 18 is at the "P" position), and the brake is operated, the shift lock mechanism 22 drives the motor in the forward direction under the control of the control device, and the cam gear 24 rotates in the forward direction via the transmission mechanism, so that the cam gear 24 is disposed at the reference rotation position from the first operation position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first operation surface 24C of the cam gear 24 to the first release surface 24A, and the first stopper 28 moves from the first movement position to the first release position to the front side against the urging force of the first spring 32 (see fig. 3 (a) and (B) and fig. 6 (a) column). When the first stopper 28 moves to the first release position (when the sensor substrate detects that the cam gear 24 is disposed at the reference rotational position), the forward driving of the motor is stopped under the control of the control device. Thereby, the insertion of the first stopper 28A into the "P" hole 20A is released, and the knob 18 is allowed to rotate from the "P" position to one direction side (the "R" position side).
When the knob 18 is disposed at the "N" position (when the sensor substrate detects that the shift position of the knob 18 is at the "N" position), and the lock switch is locked, the shift lock mechanism 22 reversely drives the motor under the control of the control device, and the cam gear 24 reversely rotates via the transmission mechanism, so that the cam gear 24 is disposed at the second operating position from the reference rotational position via the first operating position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first release surface 24A of the cam gear 24 to the first operating surface 24C, the first stopper 28 moves from the first release position to the first moving position to the rear side by the biasing force of the first spring 32, the engagement target of the second engagement surface 30B of the second stopper 30 is changed from the second release surface 24B of the cam gear 24 to the second operating surface 24D, and the second stopper 30 moves from the second release position to the rear side by the biasing force of the second spring 34 (see fig. 5 (a) and (B) and fig. 6 (E)). When the first stopper 28 moves to the first movement position and the second stopper 30 moves to the second movement position (when the sensor substrate detects that the cam gear 24 is disposed at the second operation position), the reverse driving of the motor is stopped under the control of the control device. Thus, the rear portion of the first stopper 28A of the first stopper 28 is inserted into the "N" hole 20B of the knob 18, and the rear portion of the second stopper 30A of the second stopper 30 is inserted into the upper portion of the "D" hole 20C of the knob 18, so that one direction side surface of the "N" hole 20B and the other direction side surface of the "D" hole 20C abut against the first stopper 28A and the second stopper 30A, respectively, and the rotation of the knob 18 from the "N" position to one direction side (the "D" position side) and the other direction side (the "R" position side) is locked.
When the lock switch is unlocked, the shift lock mechanism 22 drives the motor in the forward direction under the control of the control device, and the cam gear 24 rotates in the forward direction via the transmission mechanism, so that the cam gear 24 is disposed at the reference rotation position from the second operation position via the first operation position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first operation surface 24C of the cam gear 24 to the first release surface 24A, the first stopper 28 moves from the first movement position to the first release position to the front side against the urging force of the first spring 32, the engagement target of the second engagement surface 30B of the second stopper 30 is changed from the second operation surface 24D of the cam gear 24 to the second release surface 24B, and the second stopper 30 moves from the second movement position to the front side against the urging force of the second spring 34 from the second movement position to the second release position (see the column (E) of fig. 6). When the first stopper 28 moves to the first release position and the second stopper 30 moves to the second movement position (when the sensor substrate detects that the cam gear 24 is disposed at the reference rotation position), the forward driving of the motor is stopped under the control of the control device. Thereby, the insertion of the first stopper 28A into the "N" hole 20B and the insertion of the second stopper 30A into the "D" hole 20C are released, and the knob 18 is allowed to rotate from the "N" position to one direction side and the other direction side.
When the brake is not operated in a case where the knob 18 is disposed at the "N" position or the "D" position (a case where the sensor substrate detects that the shift position of the knob 18 is the "N" position or the "D" position), the shift lock mechanism 22 reversely drives the motor under the control of the control device, and the cam gear 24 reversely rotates via the transmission mechanism, so that the cam gear 24 is disposed at the first operating position from the reference rotational position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed from the first release surface 24A of the cam gear 24 to the first operating surface 24C, and the first stopper 28 moves from the first release position to the first movement position to the rear side by the biasing force of the first spring 32 (see columns (C) and (D) of fig. 6). When the first stopper 28 moves to the first movement position (when the sensor substrate detects that the cam gear 24 is disposed at the first operation position), the reverse driving of the motor is stopped under the control of the control device. Thus, the rear portion of the first stopper 28A of the first stopper 28 is inserted into the lower portion of the "N" hole 20B or the "D" hole 20C of the knob 18, one direction side surface of the "N" hole 20B abuts on the first stopper 28A, and the knob 18 is locked from rotating in the range from the "N" position to the "D" position to the other direction side (the "R" position side).
On the other hand, when the knob 18 is disposed at the "N" position or the "D" position (when the sensor substrate detects that the shift position of the knob 18 is the "N" position or the "D" position), the brake is operated, the shift lock mechanism 22 drives the motor in the forward direction under the control of the control device, and the cam gear 24 rotates in the forward direction via the transmission mechanism, so that the cam gear 24 is disposed at the reference rotation position from the first operation position. Therefore, the engagement target of the first engagement surface 28C of the first stopper 28 is changed to the first release surface 24A by the first operating surface 24C of the cam gear 24, and the first stopper 28 moves from the first movement position to the first release position to the front side against the urging force of the first spring 32 (see column (C) of fig. 6). When the first stopper 28 moves to the first release position (when the sensor substrate detects that the cam gear 24 is disposed at the reference rotational position), the forward driving of the motor is stopped under the control of the control device. Thereby, the insertion of the first stopper 28A into the "N" hole 20B or the "D" hole 20C is released, and the knob 18 is allowed to rotate in the other direction side (the "R" position side) from the range from the "N" position to the "D" position.
Further, as shown in the column (B) of fig. 6, the rotation of the knob 18 from the "R" position is not locked.
Here, as described above, in the shift lock mechanism 22, the first stopper 28 and the second stopper 30 move to the first movement position and the second movement position, respectively, and the rotation of the knob 18 from the "N" position is locked, and the first stopper 28 moves to the first movement position, and the rotation of the knob 18 from the "N" position to the "D" position is also locked. Therefore, by providing the first stopper 28 and the second stopper 30 in the shift lock mechanism 22, it is possible to lock not only the rotation of the knob 18 from the "N" position but also the rotation of the knob 18 from the "N" position to the "D" position.
Further, the cam gear 24 rotates reversely from the reference rotation position to the first operation position, the first stopper 28 moves to the first movement position, and the cam gear 24 rotates reversely from the first operation position to the second operation position, and the second stopper 30 moves to the second movement position. Therefore, the first stopper 28 and the second stopper 30 can be moved to the first movement position and the second movement position, respectively, with a simple configuration.
The first engaging surface 28C of the first stopper 28 moves due to the reverse rotation of the first operating surface 24C of the cam gear 24, the first stopper 28 moves to the first movement position, and the second engaging surface 30B of the second stopper 30 moves due to the reverse rotation of the second operating surface 24D of the cam gear 24, and the second stopper 30 moves to the second movement position. Therefore, the first stopper 28 and the second stopper 30 can be moved to the first movement position and the second movement position, respectively, by the reverse rotation of the cam gear 24.
Further, the overlapping portion 28B of the first stopper 28 overlaps the front upper side of the second stopper 30A of the second stopper 30. Therefore, the overlapping portion 28B can restrict the movement of the second stopper 30 to the upper side, and the second stopper portion 30A can restrict the movement of the first stopper 28 to the lower side, and the rattling of the second stopper 30 to the upper side and the rattling of the first stopper 28 to the lower side can be suppressed by a simple structure.
The first stopper 28 moves only to the first movement position on the rear side, and the second stopper 30 moves only to the second movement position on the rear side. Therefore, it is not necessary to move the first stopper 28 and the second stopper 30 to a plurality of movement positions on the rear side, and the movement stroke of the first stopper 28 and the second stopper 30 in the front-rear direction can be reduced, and the shift device 10 can be downsized in the front-rear direction.
In the present embodiment, the first stopper 28 is inserted into the "N" hole 20B of the knob 18, and the second stopper 30 is inserted into the upper portion of the "D" hole 20C of the knob 18, so that one side surface in one direction of the "N" hole 20B and the other side surface in the other direction of the "D" hole 20C are brought into contact with the first stopper 28 and the second stopper 30, respectively, and the rotation of the knob 18 from the "N" position to the one side surface and the other side surface is locked. However, the first stopper 28 may not be inserted into the "N" hole 20B of the knob 18, and the second stopper 30 may be inserted into an upper portion of the "D" hole 20C of the knob 18, so that one direction side surface and the other direction side surface of the "D" hole 20C abut against the second stopper 30, and the rotation of the knob 18 from the "N" position to the one direction side and the other direction side may be locked.
In the present embodiment, the shift lock mechanism 22 locks the rotation of the knob 18 from the "P" position and the "N" position. However, the shift lock mechanism 22 may also lock the rotation of the knob 18 from a shift position (e.g., the "R" position or the "D" position) other than the "P" position and the "N" position.
In the present embodiment, the shift lock mechanism 22 locks the rotation of the knob 18 from the "N" position to the "D" position. However, the shift lock mechanism 22 may also lock the rotation of the knob 18 from a range of a plurality of shift positions (e.g., a range of the "R" position to the "D" position) other than the range of the "N" position to the "D" position.
In the present embodiment, the shift lock mechanism 22 is provided on the plate 12, the face plate 14, and the case 16, and the first stopper 28 and the second stopper 30 of the shift lock mechanism 22 are engaged with the knob 18. However, the shift lock mechanism 22 may be provided on the knob 18 side such that the first stopper 28 and the second stopper 30 of the shift lock mechanism 22 engage with the plate 12, the face plate 14, and the case 16 side.
In the present embodiment, the knob 18 (shift body) is rotated. However, the shift body can also rotate or slide.
In the present embodiment, the shift device 10 is provided on the center console. However, the shifting device 10 may be provided in a floor portion of a vehicle compartment, an instrument panel, or a column cover.
